Since it’s a 2% error it can be 2% less or greater than 60% so h hours are between 58% and 62%.

Part A:

If the margin error is plus minus 2% , it means the range lies between minus 2 an plus 2 of the given percentage. As the given percentage is 60%, so the margin lies between 58% and 62%.

Part B:

A confidence interval is defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.

Hence, option C is correct.

How does adding a solute ( use only one - salt or sugar) effect the time of water to change from a liquid to a solid?
Kruka [31]

Answer:

adding salt makes the water freeze slower and evaporate slower too.

Step-by-step explanation:

While pure water freezes at 0°C (32°F), salt water needs to be colder before it freezes and so it usually takes longer to freeze. The more salt in the water, the lower the freezing point.

From the set {20, 38, 47}, use substitution to determine which value of x makes the inequality true.
vredina [299]
One way is to solve (it's easier)

x-9>29
add 9
x+9-9>29+9
x+0>38
x>38
just pick the numbers bigger than 38 as answer


47 is only number (38>38 is false)



answer is A
